-All turns are full turns (+ or -) from Base Setting

-Rake= 36’ 6 5/8” at 16 units on the Loos Gauge

-In light air the leeward lower should just be starting to sag

-As the wind increases the leeward lower will have a touch of sag and then straight when powered up

-Around 15 knots we make a big jump on the lower shrouds so that the leeward lower is tight, supporting the mast fore and aft

-The upper goes as tight as possible to keep the mast somewhat straight sideways. * Remember with the tight lowers you have to be careful when running. Keep some backstay tension so the mast stays in column


-21+ Mast will be slightly poked to weather; leeward shroud tight while going to windward
